Modeling Soil Water Movement Into Plant Roots, D. C. Slack, C. T. Haan, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

Mathematical model was developed which describes uptake of water by plant roots as a function of leaf and soil water potentials. The model was used to estimate transpiration from corn grown in a controlled environment under soil drying conditions. The model predicted daily transpiration quite well for the period modeled.
